How educational content is sourced, reviewed, updated and corrected.
Official exam notices, official institutions and reliable primary sources take priority for factual claims. Secondary sources can help explain a topic but should not override a primary source.
AI may help organize explanations or variations, but it is not treated as the canonical authority for answers. The content pipeline should preserve the underlying question/source data.
When a question or explanation is found to be wrong, the target is to correct the source record and then regenerate the public explanation rather than silently changing only the HTML.
